Title: Control circuit for controlling the timing of spark ignition of an internal combustion engine
IPC: F02P5/15
Filed: 1979-01-03
Abstract: The circuit includes a speed band selector circuit 14, 15, 16 which responds to an electrical signal T indicative of engine speed and provides an output signal indicative of which of a plurality of speed bands is occupied by the engine speed. Spark timing information for each speed band is stored in a memory 20 as a first word in units of angular rotation of the engine for the heaviest engine operating load, and second and third words indicative of the slope of straight line approximations to the curve of engine load plotted against advance in said angle units. A build-up circuit 29 responds to an electrical signal indicative of the engine operating load and computes from the second and third words a build-up word which is added to the first word and a modification word representing engine temperature in an accumulator 28 so as to derive an accumulated word in said angle units indicative of the desired spark timing. A residue angle counter 34, clocked by angle clock pulses from a clock 32 converts the accumulated word into a corresponding time delay which is used to control the timing of the occurrence of spark ignition. <IMAGE>

Title: Method and apparatus for manufacturing filled tubes, e.g. thermic lances
IPC: B23K35/40
Filed: 1980-06-26
Abstract: The present specification describes a method and apparatus for manufacturing filled tubes. The tubes are filled with elements to thus form, for example, thermic lances. Known filled tubes of this type require the elements to be held in place within the tube. However this requires the disadvantageous deformation of the tube.
